Turbine Control: Ion Exchange vs. Selexsorb

what type of turbines are you controlling??

hi, it is steam turbine..thank you for the reply...

Well I have been in the turbine control busines sfor the last 30 years.

Unfortunately the sizes of turbines I have been controlling are all in the 80 to 300 MW range driving pelectric generators.

What is your steam turbine driving?

Ion Exchange vs Selexsorb:

Relates to removal of corrosion-inducing and scale forming metal ions from boiler feed water

Ion Exchange isGeneric name.

Selexsorb =somebody's registered brand name

Ion Exchange in general is a much safer technology for steam turbine control systems. Selexsorb has two problems. It has a high percentage of sub-micron, abrasive material that can cause servo abrasion and will release metals that can react with degraded phosphate ester fluid to cause metallic deposits. This will cause valve sticking and failures, requiring you to change out the fluid and perform a system flush. The biggest concerns with ion exchange filters are manufacturing quality. The filters need to be relatively rupture proof (>100PSI) to avoid getting resin in your system. If you find a good IX technology, it will add years/decades of life onto phosphate ester fluids if you exercise good maintenance practices.
